FAQ

CMD to GBR Conversion

What are CMD files?

CMD is a text file with cutting instructions for a machine that cuts flat sheet material. It describes a job as a set of numbered panels, which are the pieces to be cut out. For each panel, the file gives the holes to be punched, the outline along which the material is cut, the lines to be drawn or marked on it, and short text labels, such as FLAP. A cutting program prepares such a file from a design, and the machine follows its coordinates to produce the pieces, so the file is not a picture but a path for a tool. The same .cmd extension is also used by Windows batch scripts.

What are GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.
